摘要

本文引入特征向量中心性来捕捉合作伙伴异质性,并考察其对城市创新的影响。通过构建2014 - 2018年中国城市共同发明专利数据库并进行实证检验,我们发现特征向量中心性对城市创新具有正向影响。技术广度和技术深度的增加是两个重要的潜在机制。反事实分析表明,创新水平较低的落后城市可以通过与其他城市,特别是与连接良好的城市建立协作联系来提高其创新生产率,这表明改善城市间创新协作网络结构的政策具有潜在收益。鄂尔多斯与赤峰的对比分析进一步证实了这一结论。

Whom You Connect With Matters: Innovation Collaboration Network Centrality and Innovative Productivity in Chinese Cities

This paper introduces eigenvector centrality to capture partner heterogeneity and examines its impact on urban innovation. By constructing and empirically testing a co-invention patent database of Chinese cities over the period from 2014 to 2018, we find that eigenvector centrality has a positive effect on urban innovation. Technology breadth and technology depth increases are two important underlying mechanisms. A counterfactual analysis shows that laggard cities with low levels of innovation can increase their innovative productivity by establishing collaborative links with other cities, especially with well-connected cities, which indicates the potential gains from policies that improve the inter-city innovation collaboration network structure. And this result is further confirmed by the comparative analysis of Erdos and Chifeng.
